| Emerson introduces new gas flow computer  Emerson Process Management introduces the new Micro Motion Model 3711 gas flow computer, the first gas flow computer to use and benefit from the accuracy of Coriolis direct mass flow measurement. Using Micro Motion patented multivariable digital technology, the system delivers gas measurement data in compliance with API MPMS Chapter 21.1, and in accordance with AGA8-92 world standards. The new 3711 solution expands the field intelligence power of Emerson’s PlantWeb digital architecture. The Micro Motion 3711 gas flow computer combines a sophisticated flow computer with Micro Motion Coriolis meters, enabling flow measurement of any pure gas or gas mixture with a total uncertainty of less than 0.5%.Because Micro Motion Coriolis measurement makes possible a large flow range, and is accurate across a wide spectrum of process and ambient conditions, one Micro Motion 3711 device can replace banks of meters of differing sizes and narrower ranges. The Micro Motion 3711 gas flow computer contains physical property data for all gases specified in current world standards. As a result, the system can measure pure or unusual gases or mixtures that are not included in AGA8-92, with measurement accuracy unattainable by other technologies. Gas properties can be specified using the customized configuration and management tool provided by Micro Motion, or real-time data can be read from an on-line gas chromatograph such as a Daniel Danalyzer or a Rosemount Analytical Model 700 gas chromatograph. Applications ideal for the Micro Motion 3711 gas flow computer include city and industrial gate stations, wellhead flow and pressure monitoring, and custody transfer of purified gases, unusual gas mixtures, or natural gas. The system is also recommended for compressor fuel gas measurement, allocation metering and control, industrial metering, and separator off gas measurement. For existing facilities, the Model 3711 gas flow computer can help manage escalating maintenance costs, reduce requirements for measurement and maintenance personnel and training, and meet the challenge of accurately delivering a wide range of product over wide swings in demand. For new facilities, the Model 3711 gas flow computer offers improved measurement with reduced installation costs. write your comments about the article :: © 2006 Construction News :: home page |
